The difference between digital and analog signals may seem straightforward, but there is a ton of nuance that defines the characteristics of the two systems.

Addressing a major roadblock in next-generation photonic computing and signal processing systems, researchers at the Harvard ...

But then you remember that it’s like 1950, and that digital computers — at least ones that can fit in an airplane — haven’t been invented yet, and that you’re going to have to do this ...

Researchers propose a wave-based, programmable 'meta-computer' that performs various analog computations at the speed of electromagnetic waves, expanding possibilities for analog computing.
